Summary

This book provides students with a clear and thorough presentation of the theory and application of structural analysis as it applies to trusses, beams, and frames. Emphasis is placed on teaching students to both model and analyze a structure. A hallmark of the text, Procedures for Analysis, has been retained in this edition to provide students with a logical, orderly method to follow when applying theory.
